Gears Galore!
This past week we have started looking more specifically at GEARS, how they work and where we can find them in everyday life!
We know that there are many different kinds of gears. Here are the ones that we have gone over so far.
Similar to pulleys, gears can be used to transfer forces and motion from one object to another. Some gear systems can also be used to change the speed and direction of the motion. Gears have teeth on them that interlock with teeth from other gears. When teeth from two gears are in contact, we say that they are meshed.
When three or more gears are used together, this is called a gear train. Gears turn on an axel similar to a wheel.

Spur Gears
In spur gears, the teeth meet on a flat surface and can change the speed and direction of motion.

Bevel Gears
In Bevel gears, two gears connect at an angle. Bevel gears are often cone-shaped. They can also change the speed and direction of motion.

Worm Gears
In worm gears, an axle or shaft has a screw thread that connects with another gears. This system is used to reduce the speed and change the direction of motion.

Rack and Pinion Gears
In rack and pinion gears, a single gear called a pinion, meets with a toothed rack. The rack may slide or stay in one place. The system changes circular motion into motion in a straight line.
